Lifecycle analysis and circular economy improvement of a Ku-band waveguide switch using R-strategies

Abstract

This study conducts a comprehensive lifecycle and circular economy analysis of a Ku-band waveguide switch, employing R9 strategies and the SolidWorks Sustainability module to uncover opportunities for environmental change. Positioned at the intersection of high-frequency mechatronics and sustainable design, the research triangulates expert insights, theoretical frameworks, and simulation-driven data to propose targeted mechanical improvements. Emphasis is placed on the material-performance-environment trade-off, with 6061-T6 aluminium alloy emerging as the preferred substrate due to its conductivity, recyclability, and low environmental burden. Modularization, additive manufacturing, and digital lifecycle assessment further reinforce the component's sustainability credentials. Value analysis and RoHS compliance evaluations validate the feasibility of the proposed redesigns. Ultimately, this work establishes a replicable framework that merges ecological foresight with engineering precision—transforming waveguide switch development into a model of sustainable electromechanical innovation.
